1. Computers store information as binary numbers, that is, a sequence of Os and 1s. Since computers have limited size of storage, computer engineers need to have a way to measure the size of information. The following terminology is used to measure information that represented in computers. Bits stand for Binary digits. A bit is the fundamental unit of computer storage. Related bits are grouped to represent different types of information such as numbers, characters, pictures, sound, and instructions Nibbles - A nibble is a group of four bits. It is the size of a hexadecimal digit. Bytes - A byte is a group of 8 bits. Words - A word is a group of 16 bits or 2 bytes. In general, how many different combinations or numbers that Os and 1s with n bits can form? That is to find a formula to determine how many numbers that n bits can form. 2. The size of storages or memory units of computers is usually measure in bytes. These units vary upon the size of storages. They can be measured as kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB) and petabyte (PB). A kilobyte is roughly one thousand bytes. But the actual number is 1,024 that is 210. That means 10 bits can form exactly 1,024 binary numbers. We use kilobyte refer to 1,024 bytes because it is easy to reference. A megabyte is roughly one million bytes. What is the actual number of bytes in a megabyte? (Feel free to use any computation device.)
